Insights

Azithromycin may help control severe preschool wheeze when inhaled corticosteroids (ICS) are insufficient. This retrospective study showed reduced symptoms and exacerbations in children treated with azithromycin, suggesting its potential as an add-on therapy.

Area of Science:

  • Pediatric Pulmonology
  • Respiratory Medicine
  • Pharmacology

Background:

  • Preschool wheeze is a prevalent condition with limited therapeutic options.
  • Current standard treatment relies mainly on inhaled corticosteroids (ICS).
  • Severe cases often remain uncontrolled despite high-dose ICS therapy.

Purpose of the Study:

  • To evaluate the efficacy of long-term azithromycin as an additional therapy for severe preschool wheeze.
  • To assess outcomes in children with severe wheeze uncontrolled by high-dose ICS.

Main Methods:

  • A single-center, retrospective study included 38 children under 6 years old.
  • Participants had severe recurrent wheeze, uncontrolled by high-dose ICS.
  • Azithromycin was administered three times weekly for 6 months as maintenance treatment.

Main Results:

  • A significant improvement in wheeze control was observed.
  • A decrease in exacerbations and daily respiratory symptoms was noted.
  • Reduced daily ICS dosage and no major adverse effects were reported.

Conclusions:

  • Azithromycin shows promise as an adjunctive treatment for young children with persistent asthma and frequent exacerbations.
  • Further validation through controlled prospective studies is necessary.
  • This finding suggests a potential new therapeutic avenue for difficult-to-treat preschool wheeze.

COPD: Management Using Bronchodilators and Corticosteroids

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids

Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

Asthma III: Clinical Manifestations

Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...

Asthma: Pathogenesis and Management

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Antiasthma Drugs: Leukotriene Modifiers

Leukotriene modifiers, or cysteinyl leukotriene receptor antagonists, are medications used to manage chronic asthma. These agents target specific inflammatory mediators produced during arachidonic acid metabolism, an essential process in generating inflammation in the body.
Leukotriene modifiers work through two distinct mechanisms:
